reproductive system
• histologically some XY ovaries appear similar to XX ovaries while others are hypoplastic with very few or no follicles
• some XY ovaries are hypoplastic with very few or no follicles
• ovaries in XY females appear smaller than in XX wild-type females when examined microscopically
• commonly detected in XY ovaries
• expression analysis indicates disruption of expression of testis determining genes
• reproductive tracts of XY mice have a predominantly female phenotype with identifiable ovaries and oviduct and uterine structures
• histologically some XY ovaries appear similar to XX ovaries while others are hypoplastic with very few or no follicles
• reproductive tracts of XY mice have a predominantly female phenotype with identifiable ovaries and oviduct and uterine structures
• sex reversed XY females are infertile; but exhibit normal mating behavior
• XX female mice are fertile
